VEHICLE-WHEEL.

To all whom t may concern' yBeit known that I, Lito KArrnR'rz, a citizen ofrthe'United States, and a residentof Morristown," county of Morris, State of New` Jersey, have invented certain new and useful Improvements in Vehicle-Wheels, of

` Whichthe follovvingis a specification.

,A `My invention relates to vehicle Wheels, and particularly to rims therefor which may be readily removedy and means for securing such rims to the felly band of a Wheel.

i .One object of my invention is to provide a demountable rim fora Wheel -Which may be readily attached and removed from the felly band thereof. j p

Another object is to provide means for `holding the demountable rim against move- I ment -relative to thel felly bandupon which it is mounted. y

`Another object is to provide a means for securing a rim to a wheel'which Will positivelyilock the rimagainst movement relatively tothe felly bandjthroughout atleast a part of the circumferential extent of the `band and rim, together With means Which Willf lockl the rim and lband in the remainder lof the circumferential extent thereof against relative motion in all directions but one, and to provide means for locking the rim and bandzagainst relative motion in that one diL rection in that part ofthe rim and band.

Y. Another object is to provide means for forcing the rim onto the band and for locking the rim in position onl the band.,

of my invention Will appear `from the 'following description taken in connection With theA accompanying drawingsforming a part of this specification, and which Will be pointed out with more particularity in the claims.` i i i n 'Io attain the objects of my invention, I provide the felly bandof a Wheel with hemispherical projections, and provide the inside of the rim with `complete hemispher- `,ical recesses throughoutav part of its circumferential extent and with hemispherical re cesses open at one side throughout the remainder ofits circumferential extent, and provide a device, including a toggle, for forcing the projections intol the open sides ofthe recesses and holding them in that position.`

felly band yhaving a demountable rim carrying a tire and attached thereto by means constructed in accordance with my inven-y tion; Fig. 2 is a sectional vievs7 on the line 2- 2 of Fig. l; Fig. 3 is a sectional view on the line 3-3 of Fig. 2; Fig. 4 is a -sectional View on the line 4-4 of Fig 2; Fig. 5 isa plan View of the lug shown in section in Fig. 2; Fig. 6 is a planvieiv of an open-sided recess; and Fig. 7 is a plan View of a complete hemispherical recess.

In the specific structure Which I have dej vised as embodying my invention, the felly VVhen it is bemade these depressions may be lput in b y j rolling the rim between cylindrical dies properly formed. The rim 4 is trough-- shaped in`cross-section, so that it may accommodatea tire 5, which may be of any form, as of the Well-known pneumaticl type having an" inner tube. The rim may either be continuous circumferentially, or it may be divided, as at 6, in order to facilitate the applying and removing of a tire or tire cas- 'ing'. The rim is perforated, so that the valv'e stem 7 may pass therethrough. On the inner face of the rim, near the opening through Which the valve stem passes, there are formed, at the points 8 for example,

hemispherical recesses. These recesses 'are formed by depressing a groove in the outer face of the rim, which groove is in the shape of the circumference of a circle. It will thus be seen that a ridge 9, shown in Fig. 7 is formed on the inner face of the rim at the points 8.' This ridge has the form of the circumference of a circle, and Within it there is formed the hemispherical recess 1 0. This recess has the same curvature as the projections 2 and has a depth which will permit it to accommodate the projections 2, so that the ridge 9 will rest upon the band 1 just at the base of the projection 2, and the ridge 9 vthe valve stem than the points 8, there are formed, the outer face of the rim, depressions in the shape'of half the circumferenceof a circle, which depressions result 1n the These recessesle areformed to accommodate certain of the projections 2 on the band, and have the same contour as the projeca tions, just as the recesses have the'same i rcontour as the projections 2. The ridges 12 are extended out at theirends'at 14 in parallel lines to permit the ridges to guide Vthe .projections as they enter the recesses 14;

. When the rim is placed upon the band, the valve stem 7 is slid through the opening in the band, so thnt'the first movement'ln. applying the yrim to the band is seen to bea substantially radial movement of the rim relatively to the band in the same plane.

Therefore, the complete hemispherical recesses 10 will it over the projections 2 Which .arenear the point where the valve stem passes through the. band. llhoserecessesV formed on the inner face of the rim which are farther'from the valve stem do not have a'radial movement relatively to the band,

and, therefore, they cannot .be formed so that they willjhave to be placed overthe projections on the band by a radial movement. For this reason, the recesses are 'formed so that they have an opening'in the side, and after the recesses 10. are 'placed over the projections 2 the part of the wheel diametrically oppositefrom the .valve stem is moved axially relatively to `the band and' the recesses 14^are slid around the projections 2.

Ity will be seeniat this point that Iihave' l described means which will prevent either relative axial or relative. circumferential movement of the rim and band in that part of their circumferential extent near the valve stem, and I have provided'means in the diametrically opposite part which Will prevent relative circumferential movement -and relative axial movement in one d1rec.

tion. In order to' force the rim and band into the same plane in that part opposite from the valve stem,'I have formed certain l of the ridges 12, as at 15, with a fiat edgey 16, substantially parallel to the edge of the lrim, as shown in Figs. 2 and 5, and have provided means o'n the band to coperate with these to force the recess 14 to fit around itscorresponding projection 2. This means mounted on the bandjconsists of a lug 17 fixed to the band. to which is pivoted a link 18 b v the pin 19.' and von' the otherend of this link 18 ispivoted the hook 20 by means 'of the pin 21.

This hook 20 extends around theedge of the band andv its end 22 is formed to fit the straight edge 16 formed. on the -in Fig.2'). will tend toy force the pin 21 s till and passing#overthewooden v said vrim and band'being-formed to'inte'rlock tively moved position. 1

ridge 12- with which the hook cooperates.

Formed integral with the link'18 is a lever arm 23 Yfor swinging the link 18A about the pin k19. y.As this link 18 swings toward the fim, itv carries the pin 21 with it and when the end 22 coperates with the face` 16 and the pin 21 is swung to a point nearer the surface of the band 1' than thepin 19 a'toggle is formed, and any tendency of the rim toslide relatively tothe band (to, the right nearer to the band .1 and still more tightly' lock the hook 2O .in position. 'Toggle def" vicesl of the kind-just described a're posi: tioned at'certain points on the band oppo- 4site the part having the-hole through which the valve stem slides, and enough of-them are provided to prevent the projections. 2 from sliding out of the' open sides of therecesses 121. V

In order-to remove the-.rimifro-m theband, the levers 23 are moved to releasethehooks 20 to the position shown in dotted lines in Fig, 2.. The hooks are then swung 'down away from the'rim and-the rim moved ax ially relatively to the band untill it is dis, engaged therefrom, and the rim is then 'moved radially relatively to the band, Aso

that the valve stem slides out of the opening through which it passes andthe projections 2 are withdrawn from the recesses 10..

While I have described and illustrated my device as vbeing used .in connection with a fla-t band, it maybe used in-connection with other shapesof bands,j and might even be mounted on a yoke connected o a'felly band lly of a wheel of the artillery type.-

While I have illustrated and described withgreat particularity a device in .which nay-invention is embodied` I do not intend that I .shall be limited to the specic details described, vbut intend' that my invention shall bel'imited only b-y the hereui'jto appended claims. f v
